REFRIGERATOR-CAR.

SPECIFICATION forming part of Letters Patent No. 439,509, dated October28, 1890. Application filed March 16, 1887. Renewed August 31, 1888.Again renewed April l0, 1899. Serial No. 347,394. (No model.)

To all whom it 11a/wy concern,.-

Be it known that I, HUGH FRANKLIN Ho- GAN, a citizen of the UnitedStates, and a resident of Albion, in the county of Noble and State ofIndiana, have invented certain new and useful Improvements inRefrigerator- Cars; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters orfigures of reference marked thereon, which form a part of thisspecication.

Figure 1l of the drawings is a horizontal Section of my refrigerator-carbody. Fig. 2 is a side elevation, with outer wall D broken at top andbottom. Fig. 3 is an end view of my car with outer wall S removed. Fig.lis a sectional view of my inlet-valve and deflector. Fig. 5 is a viewof my water-drip cup. Fig. 6 is a top view of the inner ceiling P. Fig.7 is a vertical longitudinal section of my car. Fig. 8 is across-section of my car. Fig. 9 is a detail view of doors and lock. Fig.10 is a vertical section of my lock.

My invention relates to refrigerator-cars for transporting fresh meats,fish, fruit, and the like; and it consists in the construction and novelcombination of parts, as hereinafter set forth. l

Referring by letter to the accompanying drawings, A designates acar-body, the sides B of which are each composed of four walls D E F G,which are separated by interposed studs M H to form cold-air spaces I JK. One of the intermediate walls-viz., F-is made of paper-board, and thewalls E are lined on their inner faces with paper-board L. The studs H.between the outer wall D andthe next wall E in the sides of the car-bodyare alternate studs, and their lower ends rest u pon the bottom of thecar-body. The upper ends of these studs H do not, however, extend to thetop of the car-body, but stop short of the ceiling P of the car-body andform airpassages N between their upper ends and the lower face of theceiling of the car-body. The studs M alternate with the studs H, andtheir upper ends abut against the ceiling of the car-body, while theirlower ends terminate a short distance above the fioor Q of the car-body.This arrangement of the studs is applicable to the sides of thecar-body, and is employed only between the outer wall D and the wall Enext to it. The studs R between the walls E E and F G extend from thebottom to the top of said walls, as it is not designed that a draftshall be created in the Spaces between said walls, but that said spacesshall be dead-air spaces, which are provided in order that the walls ofthe car-body may be practically non-conductors of heat and cold. Thebottom of the car-body is also constructed with double walls to formadead-air space, which latter space, however, is not connected witheither of the other spaces mentioned. At each end the car-body isprovided with four walls S T Y Z, the inner wall Z being cut away at Uin its upper corners to make provision for communication with thepassages between the walls D E. Studs XV are interposed between the endedges of the 'end walls S T, said studs W extending from the floor-lineup to the cut-away point-s U.

The intermediate studs 1 2 3 4 between the end walls S T extend abovethe ceiling of the car-body. On their inner faces along their upperedges the outer end walls T are provided with transverse timbers 5,which abut against the ends of interposed horizontal longitudinal sidetimbers 6, the outer edges of said side timbers 6 being in the samevertical planes as the edges of the ceiling P.

Between both ends of the side timbers G 6 angular deecting-pieces 7 7are interposed, Ventilating-spaces 8 being left between them, saidspaces 8 communicating with the Vertical fines or air-spaces 9 betweenthe vertical studs of the end walls of the car-body. The vertical flues10 between the vertical iiues 9 9 communicate with the air-space 11between the ceiling P and the roof 12 of the car-body, while thevertical tlues 9 9 communicate with the tortuous air-spaces vin the sidewalls of the car-body. At their lower ends the ilues 9 9 and 10 at bothends of the car-body are provided with downwardly-opening hinged valves13, which are provided with stop rests or supports 14, which cause thevalves to act as deliectors to guide the air up into the fines. On itstop the roof of the caris provided with IOO ice-boxes.

two horizontal longitudinal Ventilating-fines 15 and 16, which havecommunication with the interior of the car-body through vertical pipes17 18 near the opposite ends of said iiues 15 and 16. The verticalpipes17 18 are provided with revolving hoods 19 and 20, the latter beingprovided with vanes or sails 21, which turn the hoods 19 so that theywill always close the front ends of the horizontal opening in the topsof the Ventilating-pipes 17 18, so that the interior of the car may bethoroughly ventilated and all foul air may be carried olf.

Near the ends of the car-body I provide iceboxes 24 and 25, said boxesbeing built below and connected with the ceiling of the car. Access ishad to the ice-boxes through the roof and ceiling. Each ice-box isprovided with three vertical removable partitions 27 28 29, which aredesigned to separate the blocks of ice and prevent them from jarringagainst each other in the ice-boxes, and thus prevent the blocks of icefrom being broken, which would cause the ice to melt too rapidly,Removable covers 30 fit the mouths of the ice-boxes, the upper faces ofsaid covers being flush with the upper face ot' the ceiling P. Theopenings 31 and 32 are closed by covers 33 and 34, which, however, donot enter the air-space between the roof andthe ceiling. The ice-boxes24 and 25 are provided with curved water-discharge pipes 35 and 36-onepipe for each ice-box. The upper ends of these pipes 35 and 36 extenddown vertically. They then bend and extend along horizontally to thepoints 37, and then depend vertically to the points 38, where they againbend and extend back under the upper horizontal portion, and again benddownwardly at 39. The lower ends of the pipes project into watercups 40,which serve to seal the lower ends of the pipes when the cups are filledor partially filled with water from the melted ice in the At the uppersides of the bends in the pipes, as at 41 and 42, the pipes 35 and 36are provided with Ventilating-openings43 and 44, which admit air to saidpipes and prevent them from sweating, so that the interior of thecar-body is provided with cold dry air.

In the sides of the car-bodyI provide openings 45, which are closed bypanes 46 and 47 of glass, having air-spaces between them, and arecovered on the outside by removable slides 48, which may be slid back togive the attendant in charge of the car a view of the interior toascertain the temperature within the car, a thermometer being placed inthe car where it can be seen from the window. The interior walls of thetop of the car are also lined with paper or paper-board to render thisportion of the car practically a non-conductor of heat and cold. ends ofthe end flues maybe closedin winter to shut oit' the cold air, therebymaking the car a good winter car.

The car-doors 50 and 51 are double doors, hinged to open outwardly. Thedoors are made hollow to form dead-air spaces within them. The latch orfastening for the doors consists of two slide-bars 52 and 53, the innerends of which are pivoted between two coincident circular plates 54 55,the outer ends of the slide-bars passing through staples 56 and 57. Thecoincident plates are pivoted to the outer face of one door, and theouter plate is provided with a short lever 57 for operating theslide-bars to lock and unlock the doors. The meeting edges of thecar-doors are beveled, so that the outer door holds the inner one toplace when closed.

Having described this invention, what I claim, and desire to secure byLetters Patent,

The combination, in a refrigerator-car, of the studs I-I and the studsM, alternating and forming the tortuous air-passages in the side wall,the ues 9, having the downwardly-opening valves 13, the studs W, cutaway at U and connecting the air-passage 9 with the tortuous passage ofthe side wall, the vertical end iues l0, having the downwardly-openingValves at the bottom of the car, and the airspace 11 between the ceilingand the roof of the car, communicating with the flues 10, substantiallyas specified.

In testimony whereof I atiix my signature in presence of two witnesses.

HUGH FRANKLIN HOGAN.
